摘要
本文对电磁铁单点悬浮控制模型和整个转向架四点悬浮控制模型分别进行了仿真和优化,结果表明其阶跃响应存在明显差异,基于单点控制模型优化的控制参数在应用到转向架四点控制模型时,会引起明显的耦合现象,因此,转向架四点控制模型应作为基本单元进行响应分析进而对整车悬浮控制参数进行整定。进一步研究表明,转向架的耦合效应与其机械参数相关,如防滚梁的防滚刚度。
A comparative analysis and optimization has been carried out between the single-electromagnet levitation model and the whole bogie levitation model. The time step function responses reveal that there are obvious differences between them. It is also demonstrated that the control parameters determined by the single-electromagnet system will cause evidently coupling between each point while they were applied to the bogie system, which implies that the bogie model should be considered as the basic unit to obtain the dynamical responses and optimize the control parameters for the levitation control. Further investigations indicate that the close-loop responses in the bogie model are related with its mechanical parameters such as the coupling stiffness between modules.
